Headset has static

Plantronics model CS50 worked fine yesterday. nothing has changed since then, and today i pick it up and get static when i have a dial-tone. i swapped out phone cords, tested the alternate jack on the phone, even plugged the handset into the headset jack to cross-check. handset worked fine. the headset functions correctly until i get a dial-tone. dial tone is nearly drowned out with static.

Same thing here, with a CS70. Also lifter works fine to pick up the phone (but the static is deafening), but when the earpiece button is pressed to hang up the phone it does cut the connection but doesn't drop the handset.Same thing here, with a CS70.

Perform a reset on the headset. Hold down the mute button (the dial on the back of the headset needs to be pushed straight in), and at the same time hold down the call answer button until you see the green light on the headset blink a few times. Release both the mute button and the call answer button. See if it works now. If it doesn't, try a re-subscription (should be available in the manual).

It would depend on what headset you actually purchased. You say CS60 but
it may be the Plantronics CS50 or CS55 headset. The headsets are not
interchangeable. If you are not sure what headset you have, simply look
on the bottom of the base for the part number. On the headset you can
read what part number that is by very carefully looking under the
battery. Here is a link to open the battery.

I know this is an old post but I just want to share what I confirmed through Plantations. Hopefully it will help someone in the same situation. Sometimes, people buy replacements headsets and it should be noted the CS55 Headset does not pair with the CS50 base. While they headset looks identical, the only way to tell which headset you have is to open the battery cover and look under the battery. If you have a CS55 headset and a CS50 base, they will not pair.

The following is a cut from Plantronics web site. I hope it helps, It's just possible you have missed a setting, such as the mute switch.

The CS50 has both transmit (how you are heard) and Receive (how you hear) controls on the unit itself.

The Master Transmit controls are the ABCD switch settings on the bottom of the base. A is the lowest and D is the highest setting. You can fine tune this setting with the Plus (+) and minus (-) buttons on the back of the base that are above and below the picture of the microphone.

The Master Receive setting is on the back of the base (below the picture of the microphone) there is a 1234 switch 1 being the highest setting and 4 being the lowest setting. You can fine tune this setting by using the volume control on the headset itself. This is the rocker volume wheel on the back of the headset (opposite of the microphone).

The headset volume control also doubles as a mute switch if you press it in, instead of rocking it back and forth.

There are also configuration settings on the left hand side of the base. This is a dark grey dial with a 1234 on it. There are notches to the right of this dial. Whatever number is lined up with the notches it what setting you are on.This needs to be set to the clearest setting.

There is a silver button on the headset itself which is your “Talk button”. This is what you press to use the headset and or transfer the call from the headset back to the hand receiver.

There is also a switch on the right hand side of the base which is your the IntelliStand feature.

When the CS50 is used in conjunction with the HL10 handset lifer you can enable the IntelliStand feature.

The IntelliStand feature senses when the headset has been removed or placed into the CS50 base unit which automatically activates the Handset Lifter and enabling headset/handset mode to answer or end the call.

There is a switch towards the bottom on the right side of the base unit that will switch the IntelliStand feature On and Off.

Try a system reset:
1. Lift the headset off of the charging cradle, but make sure the headset is turned off. It will be off if the green light on the front of the base is not lit. If it's not, push the call answer button once to turn it off.
2. Push the call answer button and the mute button at the same time and hold them down. The mute button is the black little wheel at the top of the headset. Use the tip of your finger to push it straight down and hold it while holding the call answer button. A green light on the headset will flash for 2 series of flashes. Wait until the end of the second series then let go of both buttons.
3. Put the headset back on the charging cradle and wait 30 seconds. Lift it back up and try to use it. If this doesn't work, repeat one more time and then disconnect the power from the base and plug it back in.

If the Plantronics CS55 wireless headset shows that it is on, you have to make sure of the following things.

a. the green LED on the base turns on when you turn the call switch on from the headset.b. the small green LED on the side of the headset is blinking.c. the telephone headset is lifted from the cradle.d. if the headset is not charging and the Amber light on the base does not blink when you place wireless headset on it; trying placing the headset more firmly.e. If the headset is not charging and the Amber light on the base does not blink even after placing the wireless headset firmly on the charging cradle, you may need to change the battery.

Alternately you can try resetting the Plantronics CS55 wireless headset.

Reset Plantronics CS50, CS60 or CS55 Wireless Headset

If you have problems with the sound or connection of your Plantronics CS50, CS60 or CS55 wireless phone headset, you may want to try to hard reset it using the following steps:

Note: Ensure the IntelliStand switch (on the right side of the charging base) is in the - position and NOT the = position.

1. Press both the call control button and the listening volume/mute button for 5 seconds. When the indicator light blinks release both buttons.

2. Press the call control button again. The talk indicator light will again blink to indicate the headset is back to normal.
